has her own mini Santa!

The reality starlet dressed up her son Lorenzo as Santa Claus for a festive family photo -- and he's absolutely adorable!

The "Jersey Shore" star and her beau Jionni LaValle wore coordinated Christmas outfits, posing for the pic in front of their fireplace.

Snooki looked fit and fabulous in a red top, black sequin leggings and red Valentino stilettos. She topped off her look with a leopard print Santa hat -- do you expect anything less!?

Lorenzo may be one of the cutest celebrity babies out there!
